HP G5225uk won't boot.

[Gowmaster]

I was using my pc just now everything fine untill i clicked on windows alert and clicked on check for solutions to a few problems my pc had with microsoft - so I clicked and boom blue screen and it re-started it was fine so I loged in and my pc shut down again with another blue screen, then the screen went black and I shut it down manually - I checked if it was the I though it might be the graphics card so I un-installed it, then I start the pc and not even the BIOS screen pops up now + the pc starts making a beep kind of noise.

I've already tried re-seting the CMOS still wouldn't work same thing with the batery, For the record I recently had an HD failure and was send a re-placement and with the new one i was back to square one, everything worked fine untill just 20 minutes ago.

Does anyone have any idea why this happen? or what the problem might be?

and if so, How can I solve this problem? please I need help.

btw the beep goes in a 2 short beeps - 2 seconds pause - then again, might there be a problem with my RAM, GPU or PSU?
